First off i wanna thank Bill over at Stage3 for talking with me about this product and getting me all taken care of. I was worried about this product cuz people said it was too hard to handle, 0-15 psi boost instanty? ect ect ect! NOT TRUE!! LOOK if you punch it, its gna do that, so why would you write a bad review about this product!! if your easy on it, it takes off normal, maybe a little quicker, but your adding HP and TORQUE. WHAT DO YOU EXPECT? haha I got the AFE stage 2 intake and the scocher, i think this combo is awesome! you can hear the intake and turbos good, not to lound and not too quiet! its 4x4 and i have 3.31 gears and 22x11 wheels with 305/45s on it. 45 or 55 i cant member haha, anyways they are 32.5x12 inch tires. my gas mileage went down bout 2.5 mpg when i put this wheel tire combo on, now with the scorcher and intake its gone back up 2 mpg maybe more... well see only got the play with it one day so far...But anyways, so if anyone is wondering about this product, its good to go, it adds power through the whole curve, and if you punch it, its gna go! If people cant handle the power they shouldnt have gotten a tuner that adds more power, lol. i love i can take it off drive a few hundred miles and warrenty work is all good again!
